General Note:

a. Total of 91 C&NW units went to UP at merger.
b. C&NW records show 4344 and 4457 as being unrebuilt GP7s; UP records show them as GP7R.
c. Assigned UP 400-489 in the post-merger renumber plan; no units renumbered prior to retirement.
d. C&NW 4120 and 4190 remained in extended service on UP because they are assigned to the former C&NW coach yard in Chicago, Illinois Because of their low end step design, they work well with the Metra bi-level commuter cars. The units were also equipped with C&NW's ATC and ATS train control used along the commuter corridor.
